ABSTRACT:
The production of liquid hydrocarbons from coal is significantly enhanced by alkylating or acylating the coal prior to subjecting the coal to liquefaction conditions. The introduction of aliphatic hydrocarbon radicals or acyl radicals, including carbon monoxide, into the coal structure is believed to permit more of the coal to undergo liquefaction at suitable liquefaction conditions. The alkylation or acylation reactions can be conducted in the presence or absence of added or extraneous catalysts.
